I-β-Nicotinamide mononucleotide (β-NMN) yinto eyenzeka ngokwemvelo emzimbeni womntu odlala indima ebalulekileyo kwiinkqubo ezininzi ze-biological. I-β-NMN ifumene ingqwalasela kwinkalo yophando lokuchasana nokuguga ngenxa yesakhono sayo sokuphucula amanqanaba e-NAD+. Njengoko sikhula, amanqanaba e-NAD+ emzimbeni ehla, ekucingelwa ukuba sesinye sezizathu zeengxaki zempilo ezinxulumene nobudala.
